Process Code Comments to Generate Quick Help/Tooltip

I think it would be cool if you could specify comments at the top of your class or above a method/function to generate a quick help/tooltip for the function or class.

Heres a example for a function where you would add these comments above the function implementation and when you call the function in another file you can control click the function name to view the quick help/tooltip.

///Summary

///Description: {description}
///Params: {params}
///Return Type: {return type}
///Public/Private: {scope/access modifier}

I think this would be very helpful for some people. Just a thought but I can see it being a big request.
